| Have been following Iowa Soybean Association side-by-side strip trials for liquid vs anhydrous. Substantially more efficient use of anhydrous translates to less dollars per bushel of yield (a lot if you side-dress) and a reasonable likelihood of environmental bonus points in future government payment programs. Anhydrous is hazardous, but not nearly as dangerous as some would have you believe. If it was, a significant portion of the farmer population would be both sight impaiered and lung function impaired. In one of the two symposia below (2nd I believe), Norm Olson summarized the history behind its hazardous classification.

Yes, more equipment but no saddle tanks, lots of acres per tank (both large tank size and reduced rate) means fewer hassles and faster application.
